<p>An open-end wrench for quickly turning an object (A) includes a driving end (10; 10a; 10b; 10c) including a first jaw (11; 11a; 11b; 11c) and a second jaw (12; 12a; 12b; 12c) which cooperate together. One of the first and second jaws includes a recess defined therein. Further, a movable engaging member (20; 20a; 20b; 20c) includes a body (21; 21a; 21b; 21c) pivotally fixed in the recess by a pivot (22; 22a; 22b; 22c). The body is in a surface contact with a lateral wall of the recess, and the recess supports the body. The pivot is inserted through the body and is fixedly engaged with a wall of the recess. Further, an elastic member (30; 30a; 30b; 30c) resiliently engages with the movable engaging member. Furthermore, the open-end wrench is turned in a first turning direction to turn the object and in a second turning direction to move relatively to the object.</p> |
